Cloud cover keeps the surface of the earth relatively cool by reflecting solar irradiation, that would warm the earth’s surface up if it got through, back into space.
Certain types of radiation from space nucleate clouds on earth by creating cascading collisions among molecules of gas high in the atmosphere. To the extent such radiation is deflected away from earth, we get less cloud cover, and average temperatures rise. To the extent such radiation is not deflected but is instead allowed to strike the earth’s atmosphere unimpeded, we get more cloud cover, and average temperatures drop.
In this regard, once again, the behavior of the sun determined which way we go, in terms of lesser or greater average amounts of cloud cover.
A more active sun from an electromagnetic perspective (the shorthand version of this is: gobs and gobs of sunspots before, during and after Solar Maximum), tends to extend its protection around earth more forcefully and consistently, thereby deflecting relatively more of the cloud-nucleating space rays, thereby decreasing the average extent and persistence of atmospheric cloud cover, thereby increasing average surface temperature.
The opposite is also observed.
A less active sun, from an electromagnetic perspective (the shorthand version of this is: a relative paucity of sunspots before, during and after Solar Maximum) tends to withdraw its protection around earth, or make it less consistent,, thereby deflecting relatively fewer of the cloud-nucleating space rays, thereby increasing the average extent and persistence of atmospheric cloud cover, thereby decreasing average surface temperature.
Yes, this knowledge and the research that produced it is actively being suppressed.
Why so vague? Spit it out! The type of ionizing radiation that contributes to cloud-formation is: Cosmic rays!
Your statements strongly imply that the concentration of these gases stands in direct relation to the "deflection" of this ionizing radiation - and that those concentrations very.
So my question now to you: What gases in Earth's (upper) atmosphere - with a variable concentration! - mask / deflect / absorb / trap this ionizing radiation and thus affect the nucleation of clouds in the troposphere?
